Description Niraj Modi

Raising bug to capture open issues discussed in https://git.eclipse.org/r/c/platform/eclipse.platform.swt/+/174084

Also below JUnits fail to execute:
test_OpenWindowListener_evaluateInCallback
test_LocationListener_evaluateInCallback

>> These 2 fail due to the fundamental limitation of WebView2. WebView2 callbacks are not reentrant, only one can be received at a time. I.e. it's impossible to receive an event callback, request JavaScript evaluation from it and then receive evaluation result callback, since the first callback hasn't finished yet.

Not sure if these can be workaround, we expect a fix from Microsoft Edge "WebView2" side.
